The water heater equipment starts to be powered on, the water heater starts to be in a standby state, the processor detects whether the user starts to use water, and if the processor detects that the user does not use water, the water heater is proved not to be started, and the water heater is still in the equipment standby state. When the processor determines that the user is beginning to use water in a water use state, the water heater detects whether periodic air replenishment is needed.
The processor obtains the volume V1 of a gas tank in the micro-bubble water generating device of the water heater, the air ratio C1 of the gas tank and the flow rate L of the air pump per minute, wherein the optimal value of the air ratio C1 of the gas tank is between 0.6 and 0.8. The processor determines the air supply period according to formula (1) through the obtained parameters, wherein the formula (1) is as follows:
after the air supply period is calculated by the processor through the formula (1), the obtained result is compared with a preset range, the preset range of the processor is 30-60 seconds, if the result calculated by the formula (1) is not out of the preset range of 30-60 seconds, the water heater is judged not to need periodic air supply, if the result calculated by the processor through the formula (1) is within the preset range of 30-60 seconds, the water heater is judged to need periodic air supply, and the air supply period is preferably 45 seconds.
When the processor detects that the water heater needs to be periodically supplied with air, the water heater control board obtains the local ambient temperature from the cloud end through the Wi-Fi module, and also obtains the ambient temperature through the ambient temperature detection module of the machine.
And after the processor obtains the ambient temperature, the outlet water temperature is correspondingly increased for 2 seconds according to the ambient temperature. The processor adjusting the temperature of the retained water in the gas tank of the micro bubble water generating device according to the environmental temperature comprises: when the ambient temperature is lower than a first preset temperature, increasing the temperature of the reserved water by a first numerical value; when the ambient temperature is higher than the first preset temperature and lower than the second preset temperature, increasing the temperature of the reserved water by a second value; and when the ambient temperature is higher than the second preset temperature, increasing the temperature of the reserved water by a third value.

If the water heater detects that the ambient temperature is 20 ℃ and the current residual water temperature of the water heater is 37 ℃ through the environment detection module, the target temperature is 39 ℃, the processor adjusts the ratio of cold water and hot water of the water heater by controlling and adjusting the opening of the valve core of the thermostatic valve of the water heater, and the current water temperature of the residual water at 37 ℃ is increased to the target temperature of 39 ℃ and is kept for 2 seconds. If the processor detects that the ambient temperature is 32 ℃ and the current water temperature of the water heater is 37 ℃ through the environment detection module, the target temperature is 38 ℃, the ratio of cold water and hot water of the water heater is adjusted by adjusting the opening of the valve core of the thermostatic valve of the water heater, and the current water temperature of the stored water at 37 ℃ is increased to the target temperature of 38 ℃ and is kept for 2 seconds.

After the water outlet temperature corresponding to the environment is increased for 2 seconds, the air pump of the micro-bubble water generating device is started to supplement air for the air tank of the micro-bubble water generating device, the micro-bubble water generating device supplements air for the water heater according to the air supplementing period determined by the processor, meanwhile, the electromagnetic valve between the air tank of the micro-bubble water generating device and the water outlet end of the thermostatic valve is closed, the electromagnetic valve is closed, the air pump of the micro-bubble water generating device can be prevented from pouring the stored water back into the thermostatic valve during air supplementing, the position of the valve core is kept unchanged by the motor of the thermostatic valve, and the temperature of the stored water is kept at the increased target temperature.
And after the air supply time is up, the processor controls the water heater to stop the air supply of the air pump and simultaneously opens the electromagnetic valve. The duration of the air supply is preset to be 1.5-3 seconds by the processor. And after the air supply time reaches the preset time of 1.5-3 seconds, the water heater controls the air pump to stop supplying air and simultaneously opens the electromagnetic valve.
